Clinical Trial Summary

Muscle pain is frequently attributed to myofascial pain syndrome (MPS) in which myofascial trigger points (MTrP) are a characteristic feature. Dry needling is a frequent clinical practice to manage MPS but few evidence is published about percutaneous electrolysis effects for the treatment of MPS.

This is a randomized clinical trial with 3 parallel groups: 1) High intensity-short time percutaneous electrolysis; 2) Low intensity-long time percutaneous electrolysis; 3) dry needling control group.

Description:

The current study aimed to evaluate changes in rectus femurs active trigger points and patellar tendon pain pressure thresholds and subjective anterior knee pain perception after application of two percutaneous electrolysis methods using a same charge (high intensity and low intensity) compared to a dry needling group in patients with patellofemoral pain syndrome (PFPS)

Fifteen patients diagnosed with unilateral PFPS were divided in two experimental groups (high intensity percutaneous electrolysis and low intensity percutaneous electrolysis) and one active control group (dry needling. The duration of the study was 7 days with only one intervention. Pain pressure thresholds were assessed using an algometer before the intervention, immediately after the intervention and after 7 days and a Visual Analogue Scale was used before the treatment and after 7 days to rate the subjective anterior knee pain perception. Also a VAS was used to rate the pain perception during the intervention
